Identify evidence of due professional care

Difficulty

Easy

Key idea: Engagement workpapers document the planning, testing, evidence, and supervisory review that show auditors actually applied due professional care.

How to reach the answer

1. Due professional care concerns how the work was performed: its extent, rigor, and the consideration given to risks and evidence.
2. Evidence of how work was performed comes from the documentation produced during the engagement.
3. Workpapers record procedures, sampling, analysis, conclusions, and reviewer sign-offs.
4. The charter, the code of ethics, and the final report do not show the rigor of the work behind it.

Each option

• AIncorrect. The charter defines purpose, authority, and responsibility but says nothing about how carefully a given engagement was performed.
• BCorrect. Workpapers document the procedures, evidence, and supervision that demonstrate due care was exercised.
• CIncorrect. The report communicates results but summarizes them without showing the work and judgment that support them.
• DIncorrect. The code of ethics states expected conduct, which is a commitment rather than evidence of performance.

Common trap: The audit report is the visible output, so it seems like proof of quality, but it does not document the underlying work.

In practice: Quality assurance reviewers and external assessors test conformance mainly by inspecting engagement workpapers and evidence of supervisory review.

Remember: If you need to prove how the work was done, point to the workpapers.
